Abstract
A heavy duty heat exchanger consisting of a large number of plates of tapered cross-section, selectively provided with essentially lengthwise parallel grooves and land areas at the lengthwise edges. Upon being stacked together and joined, the plates form an inherently leaktight, rugged and compact heat transfer core with axially directed fluid passages and integral with it two fluid transition zones, all of radially symmetrical, annular cross-section, throughout. Very large fluid flow rates can be accommodated and very high heat transfer effectiveness attained without increased design complexity or cost escalation.
Claims6
A heavy duty annular heat exchanger with multiplicity of parallel, essentially axial fluid passageways of small cross-section for heat transfer between a plurality of fluids in a high pressure environment, comprising:
- a multiplicity of solid plates, in plurality of distinct sets, each said plate having a tapered cross-section taken in a plane perpendicular to the longitudinal axis of the heat exchanger, said plates being selectively provided with a multiplicity of essentially parallel, longitudinally disposed grooves of relatively small cross-section for defining fluid passages, wherein grooves adjacent plate edges define therewith land areas serving as primary plate joining surfaces and interior grooves define therebetween heat transfer fins which also serve as load carrying members;
- said plates being juxtaposed and joined together to form a self-enclosed structure of annular, radially symmetric cross-section, defining a heat transfer core and fluid transition zones with a multiplicity of distinct fluid flow passageways;
- and
- means for introduction and discharge of a plurality of distinct fluids to and from their respective passageways.
